Store waveform peaks inline in audio_versions (JSONB columns) so WaveSurfer
can render the waveform immediately on page load without waiting for audio
decode. Adds a 100-point mini-waveform for version selector thumbnails.
Backend:
- Migration 0006: adds waveform_peaks and waveform_peaks_mini JSONB columns
- Worker generates both resolutions (500-pt full, 100-pt mini) during transcode
and stores them directly in DB — replaces file-based waveform_url approach
- AudioVersionRead schema exposes both fields inline (no extra HTTP round-trip)
- GET /versions/{id}/waveform reads from DB; adds ?resolution=mini support
Frontend:
- audioService.initialize() accepts peaks and calls ws.load(url, Float32Array)
so waveform renders instantly without audio decode
- useWaveform hook threads peaks option through to audioService
- PlayerPanel passes waveform_peaks from the active version to the hook
- New MiniWaveform SVG component (no WaveSurfer) renders mini peaks in the
version selector buttons
Fix: docker-compose.dev.yml now runs alembic upgrade head before starting
the API server, so a fresh volume gets the full schema automatically.

- audioService: replace 'as any' with 'as unknown as AudioService' in
resetInstance() to satisfy @typescript-eslint/no-explicit-any
- SongPage: add isReady to spacebar useEffect deps so the handler always
sees the current readiness state
- useWaveform: add containerRef to deps (stable ref, safe to include);
suppress exhaustive-deps for options.onReady with explanation — adding
an un-memoized callback would cause initialization on every render

When navigating away from SongPage and back to the same song, the container
div is a new DOM element but the URL is unchanged. The previous early-return
(currentUrl === url) would skip initialization entirely, leaving WaveSurfer
pointing at the detached old container — nothing rendered.
Fix: track currentContainer alongside currentUrl. When URL matches but container
has changed, call wavesurfer.setOptions({ container }) which moves the existing
canvas into the new container without reloading audio or interrupting playback.
WaveSurfer v7 renderer.setOptions() supports this: it calls
newParent.appendChild(this.container) to relocate the canvas div.
Three paths in initialize():
1. Same URL + same container → no-op
2. Same URL + new container → setOptions re-attach (no reload)
3. Different URL → full teardown and reload

When WaveSurfer.destroy() is called it aborts its internal fetch AbortController.
If the same HTMLAudioElement is immediately passed to a new WaveSurfer instance,
the aborted signal is still draining — the new instance's loadAudio call sees it
and throws AbortError: signal is aborted without reason.
Fix: create a new <audio> element for every new song via createMediaElement().
destroyWaveSurfer() removes and discards the old element (inside the existing
try/catch so jsdom test noise is suppressed). The new element is still appended
to document.body so playback survives SongPage unmounts.
resetInstance() now delegates to cleanup() to properly tear down the media
element between tests.

Bug 1 — playback stops on navigation:
WaveSurfer v7 creates its <audio> element inside the container div. When
SongPage unmounts, the container is removed from the DOM, taking the audio
element with it and stopping playback. Fix: AudioService owns a persistent
hidden <audio> element on document.body and passes it to WaveSurfer via the
`media` option. WaveSurfer uses it for playback but does not destroy it on
WaveSurfer.destroy(), so audio survives any number of navigations.
Bug 2 — stale playhead/duration when opening a new song:
initialize() called destroyWaveSurfer() but never reset the store, so the
previous song's currentTime, duration, and isPlaying leaked into the new song's
load sequence. Fix: reset those three fields in the store immediately after
tearing down the old WaveSurfer instance. cleanup() also now resets duration.
Bug 3 — excessive console noise on mobile:
Remove console.warn from play() (silent return when not ready) and from
useWaveform's play() wrapper. Only console.error on actual errors remains.

playerStore: remove currentPlayingSongId/currentPlayingBandId/setCurrentPlayingSong.
Single pair (currentSongId/currentBandId) now set exclusively when play() is
called, not when the page opens. This means MiniPlayer and sidebar links only
appear after audio has been started — correct UX for a "now playing" widget.
audioService: play() calls setCurrentSong instead of setCurrentPlayingSong;
cleanup() clears it. Remove isReadyForPlayback() and canAttemptPlayback()
aliases — all callers now use isWaveformReady() directly.
useWaveform: remove setCurrentSong call from init (store updated by play()
now); restore-playback snapshot reads currentSongId/currentBandId.

audioService.ts rewritten from ~850 lines to ~130:
- Remove custom logging system with throttle that suppressed ERROR logs
- Remove AudioContext management entirely (initializeAudioContext,
handleAudioContextResume, setupAudioContext, shareAudioContextWithWaveSurfer,
ensureAudioContext). WaveSurfer v7 owns its AudioContext; fighting it caused
prod/dev divergence and silent failures.
- Replace 5-state InitializationState machine + split promise with a single
isReady boolean set in the 'ready' event handler
- Remove retry/debounce logic from play() — these are UI concerns
- Remove dead methods: canPlayAudio (always returned true), getWaveSurferVersion,
updatePlayerState, getAudioContextState, setLogLevel
- Extract destroyWaveSurfer() helper so cleanup is one place
- MiniPlayer now passes songId/bandId to play() (was calling with no args)
- SongPage spacebar handler simplified: just checks isReady from hook
- SongPage no longer imports audioService directly

- useWaveform: remove globalCurrentTime/globalIsPlaying from useEffect deps;
WaveSurfer was re-initializing every 250ms while audio played. Dep array
is now [url, songId, bandId]. Store reads inside the effect use getState()
snapshots instead of reactive values.
- useWaveform: move animationFrameId outside the async function so the
useEffect cleanup can actually cancel the RAF loop. Previously the cleanup
was returned from the inner async function and React never called it —
loops accumulated on every re-render.
- audioService: remove isDifferentSong + cleanup() call from play(). cleanup()
set this.wavesurfer = null and then play() immediately called
this.wavesurfer.play(), throwing a TypeError on every song switch.
- audioService: replace new Promise(async executor) anti-pattern in
initialize() with a plain executor + extracted onReady().catch(reject) so
errors inside the ready handler are always forwarded to the promise.
- audioService: remove currentPlayingSongId/currentPlayingBandId private
fields whose only reader was the deleted isDifferentSong block.
